Crenel function

Do you know what a castle looks like? With the tall walls and pointy towers? Well, imagine looking at the walls of a castle from a bird's eye view - like looking straight down on them. If you look closely, you can see that the walls have little bumps and spaces in them that make them look like teeth.

Now, imagine drawing a line on the wall that goes up and down and passes through all these little bumps and spaces. That line is called a crenel function. It's like taking an imaginary rollercoaster ride along the castle wall!

People use crenel functions in math and science to help them study waves and vibrations. Just like the bumps on a castle wall, some things in science have ups and downs, like sound waves or the way light moves. By using crenel functions, scientists can better understand how these waves and vibrations work.

So, remember - a crenel function is like a rollercoaster ride along a castle wall, and scientists use it to study waves and vibrations!
